SPECIFICATION forming part of Letters lPatent No. 5597,03?, dated March 24, 1896.V

Application filed December 28', 1895. Serial No. 573,635. (No model.) i

To a/ZZ whom t may concern:

.Be it known that I, BENJAMIN LOUIS To- QUET, a citizen of the United States of America, and a resident of Westport, Fairfield county, Connecticut, have invented an Im'- proved Electrical Connector, of which the following is a specification.

The obj ect of my invention is to provide for electrical conducting-wires a simple, inexpensive, and easily-applied joint or connector whereby a perfect mechanical and electrical connection can be made.

In the accompanying drawings, Figure lis an outside view of one form of my connector as ready for use. Fig. 2 is a longitudinal section' of the tube, showing the ends of the metallic conductors which are to be connected in place, but before the joint is made. Fig. 3 is a sectional view of the same after the joint has been made. Fig. 4 is a corresponding outside view of the same. Fig. 5 is a view at right angles to Fig. 4 and showing one half of the tube in section. Figs. 6, 7, and 8 are transverse sectional views at the several points indicated in connection with Fig. 5.

Figs. 9 and 10 are views of 'modified forms ofv my connector drawn to a smaller scale.

Referring to Figs. 1 and 2, A and A indicate the bare ends of the copper or other electrical conductors to be connected, while B is the tube or sleeve f (preferably of similar metal) by means o f which the joint is effected. The internal diameter of the connecting-tube B for a given gage of wire is of a size to just allow ofthe convenient insertion of the ends of the wires A and A of that gage, as indicated in Fig. 2, the fit being a close one.

When the ends of the wires have been inserted in the tubes'until they nearly meet about the center, I indent both the tube and the contained wires by a suitable tool, such as a pair of pliers, which will crush each wire end at one or more points within the tube to a greater width than the normal internal diameter of the tube or sleeve.

In Figs. 3 to 5 I'have shown the tube and contained Wire ends as crushed in together at four points, two for each wire end. The action is such as to not only crush and iiatten out the tube or vsleeve B in forming the opposite indentations b, vas shown in Fig. 4, but also the parts'of the wire ends between these'opalso get a good electrical joint, because of the metallic union brought about by the crushing together and fiattening jointly of the wires and tube. These connectors can be made either straight, as shown in F1g.`1, or 1n any other suitable form, such as the Tl form for' jointing three wires, as illustrated in Fig. 9,

or the cross form illustrated in Fig. 10. The connection may be used in terminals and branches, as well as connecting two wire ends, as will be readily understood. When straight.

connectors are used, such as illustrated-in Figs. 1 to 5, I prefer to provide each tube with a central internal stop or stops z, which may be most conveniently formed byslightly indenting the tube, as shown in Figs. 1, 2, 4, 5, and 7. The purpose of these stops is to locate the ends of the wires at desired points within the tubes without having to measure them, and thus time will be saved in making connections. I am aware that tubes or sleeves have been used for electrical wire-connectors, but in all such cases, so faras I am aware, it has been sought to secure the necessary electrical and mechanical connection by twisting or bending the tubes. Either of these operations involves no little labor and time and the use of powerful instruments, and the joint when finished does not oder a perfect safeguard against pulling apart and does not insure a perfect electrical connection. In my joint, however, since the wire ends are flattened within the tube until at points their width exceeds the normal inside diameter of the tube, it is practically impossible to pull the joint apart without either breaking the wire or the tubo, and, as I have already explained, this same crushing and attening of the tube and Y where there would not be room to either twist or loeniU such connection, as it is only necessary, with my joint, to reach it with the emi of the tool. The joint can' be easily tapped and is not cumbeieome. lt Leen be need to splice n broken Wire, es the Wires do not overlap each other. i

l claim es my inventionl. A. joint for electrical conductors consisting of a tube fitting over adjoining ende of the conductors, Tooth tube and conductor ende being indented, widened and ciusliecl toa-ether7 nt points, substantially es described.

2. A tube for n joint for electrical conductors' indented to forni en internal central stop or stops, substantially ae and for the purpose described.

ln testimony whereof l lieve signed my nenne to this specification in the presence of two subscribing Witnesses.
